UNITED STATES ATENT Fries,

JAMES ALBERT HOLLY, OF FINE BLUFF, ARKANSAS.

'SAFETY-ENVE'LO P.

SPECIFICATION forming part of Letters Patent No. 590,890, dated September 28, 1897.

Application fiiea March 16, 1397.

a citizen of the United States, residing at Pine Bluff, in the county of Jefferson and State of Arkansas, have invented certain new and useful Improvements in Safety-Envelops; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

My invention relates to a safety-envelop; and the object is to provide a device of this character which may be cheaply made and which will prevent the envelop being tampered with by unscrupulous persons without detect-ion.

lVith this object in view the invention consists of certain features of construction and combination of parts which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure l is a view of the blank from which my envelop is made. Fig. 2 is a similar view of a comleted envelo Fi 3 is a sectional view on P P a the line 00 a; of Fig. 2.

In the drawings, 1 represents the blank, which consists of a rectangular strip of paper which may be reeled off and cut to the de sired size without the loss of any paper whatever.

As shown in Fig. 2, I have provided the front of the envelop with a series of perforations at, which are arranged in vertical rows along the ends of the envelop and in a horizontal row along the flap of the envelop. In Fig. 2 I have shown these holes covered by small paper disks b, which are of considerably lighter weight than the body of the envelop and therefore more easily torn than said envelop and preferably consist of tissue-paper.

The ends and flap of the envelop are gummed together, and to prevent a person steaming the ends 'or otherwise dampening the gummed portion of the envelop, thus ob- Serial No. 627,814. (No model.)

taining access to the contents of the envelop without detection, I have provided the weak paper disks, whereby should it. be attempted to open either the flap or the ends of the envelop the weak paper disks, having been pasted over said holes and to the back of the envelop, will be torn, thus clearly showing that the envelop has been tampered with.

The paper disks are of a color contrasting with that of the envelop, and in some instances I prefer to color them with some soluble coloring-matter, whereby when subjected to steam or moisture the coloring-matter will run, thus showing that the envelop has been tampered with. These holes may be arranged in the form of letters denoting suitable words, or they may be arranged in the form of ornamentalor conventional figures. A convenient way to open the envelop is 'to provide a cord 2, the lower end of which is sealing-flap of the other body-flap being provided with a row of perforations, and weak paper disks provided with a soluble coloringmatter contrasting with the color of the envelop, said disks pasted over the perforations and to the opposite flap, substantially as shown and described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
